Looking for some help please.
I am re-powering a wood lathe with a 3-ph motor and VFD, the original motor pulley is 14mm shaft, new motor is 3/4" shaft size, the old pulley doesn't have enough meat on it to bore it out, and besides it is only a 3 groove poly-V belt ( a bit light duty).
So, I need to source new pulleys, or make my own.
I want 3 steps, 5 groove belt, maximum diameter step 70mm.
Does anyone know somewhere I might be able to buy something to suit my needs ?
The other option is to turn my own, I have a metal lathe, so can probably do the job if I have to.
The questions I have here, are ,
1- what material would be best. The originals are aluminium, would mild steel be better ? I assume cast iron would be best, but I don't like my chances of getting any to suit around here.
2- Would it be best to grind a tool with the profile of one of the grooves and cut each groove separately ?
I will probably have more questions later if I decide to make my own, but any help now is much appreciated.
